[QUOTE="nvschütze, post: 1823676, member: 110896"] I also uniform the flash hole because I believe the chamfer allows the primer flash to spread-out in a cone and start the combustion at the bottom of the powder column, as opposed to having a spire of flame shoot upwards through the powder column and ignite the whole mess of propellant at once. A slow ignition builds a consistent pressure. A dagger of flame up through the powder causes high pressures and inconsistent bullet velocities. At least that's what I believe... [/QUOTE]
